This invention relates to new and useful Fig. 4 is a horizontal sectional view taken improvements in stoves and furnaces. on the line 4 4 of Fig. 1,

Disposed with- Fig. 3 is a vertical sectional view taken on in the vhollow jacket formed by the walls 14, the line 3-3 of Fig. 2, 15, 18 and doors 22, 23 is a cylinder 24 which 100 embraces the stove A. The front of the cylinder 24 is provided with upper and lower doors 24a and 24h. Lateral passages 25, 26 afford communication between the interior of the cylinder 24 and the vertical-side passages and 17 respectively. These passages 25, 26 are centrallylocated between the front and rear walls of the jacket, and at the eX treme upper port-ion of said jacket. The jacket includes a removable and imperforate top 27 which extends 'between andinerges with the outer side walls 11 and 12, the front walls 20, 21 and the rear outer wall-113.` The' inneil side walls 14, 15' andthe inner rear wall 18 are also united at their upper edges to` said topv 27. y The lowerportions of ,the vertical passages 16, 17 and 19.1are closed bybottom walls 28, 29 and 30 respectively. f

Located in the rear of: .the jacket andat the npper endA of and in. direct communication with the vertical rearpassage' 1'9`is an outlet 31 which is adapted for connection with the chimney flue andV which is provided witha damper 31a.. Located in therespective verf Vrtical side passages 16and 17 betweenthe lateral passages 25, 26 and the verticalrear passage 19, are downwardly extending baffle plates 32 .and 33, the upper endsbeing united with the top 27, the lower ends being` i .i curved forwardly as at 34, 35 and terminating above the bottom wallsf28`,29 of thefvertical side passages 16, 417, andthe sides of the baiiie plates being united with the associated inner and outer side walls of the acket.

From thel foregoing, it will be observed that the products of combustion will,` pass outwardly from the stove A intothe cylinder l 24 and thence laterally in opposite directions through the lateral passages`25 and 26into the vertical side j passages 16 and 17. The products of .combustion will then .pass downwardly throughV the yvertical side passagesvl and 17 and thence around or under thefballes 34 and 35, `thence rearwardly into lthe vertithetiiue through theoutlet opening 31. B

lVhen starting the fire in the stove, it may be desirable to have direct communication between the stove and the outlet 31,. and to this end, I have provided an opening in the cylinder 24 at a point in registration with .I

the outlet 31. rilhe opening 40 is in communication with the outlet 31 through the medium oiI a rearwardly extending' lateral passage 41. The opening 40 is controlled by a damper 42 which is fixed to a horizontal .shaft43. journaledin the jacket and having one end extending beyond the jacket and terto thcr lower portion 'of the acket andv ex.4
